testsuite problems

[Richard Earnshaw]

I'm currently seeing the following when running the testsuite.

Running /nfs/sun18/work/rearnsha/gnusrc/src/gdb/src/gdb/testsuite/gdb.base/
corefile.exp ...
failed to get controlling terminal using TIOCSCTTYparent: sync byte write: 
broken pipe

However, it only occurs if I'm running the whole suite.  If I just run 
corefile.exp it completes ok.

I seem to remember something like this once before (on another testsuite); 
IIRC it occurs when a connection to a child isn't shut down cleanly after 
a test (normally because the test failed in some way); the controlling pty 
isn't released cleanly and we then eventually run out of ptys.  Could this 
be the problem here? -- certainly I'm seeing rather a large number of 
failures at the moment, since I'm in the middle of trying to raise the ARM 
code to multi-arch 1.
